Impeller- Series 5560 pumps have semi-open type impeller with heavy vanes for outstanding performance. Back pump-out vanes on a semi-open impeller reduces pressure behind the impeller and limits axial thrust.

Power Frame- Heavy duty, one piece cast iron, precision bored and machined to assure alignment of the rotating assembly. Series 4310-11 pumps are short set design. Series 5560 are available in 9”, 12”, and 15” extension lengths below the support plate.

Shaft- High strength shaft is extra heavy for maximum loads with minimum deflection. Impeller is keyed to shaft and locked with impeller nut or large cap screw.
